'T 0 all whom t may concern.'

Be it known .that I, GEORGE V. Porz, a citizen of the United vStates, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented new and useful Improvements inMeans for Feeding and Cutting Ice-Cream, of which the following is a specification, the principle of the invention being herein explained and the best mode in vwhich I have contemplated applying that principle, so as to distinguish it from other inventions. v

My invention relates to machines for feeding and cutting ice cream. Particularly, my invention relatesl to means for cutting a large block of ice creaminto portions serving to iill individual orders. The invention is particularly vuseful in so cutting varicolored or iNeapolitan cream.

The annexeddrawings and the following description set forth in detail certain means embodying my4 invention, the disclosed means, however, constituting but one of the various mechanical forms in which the principle of the inventionV may be employed.

In said annexed drawings: 'y

l Figure 1 represents a plan view of my 1n- A vention Fig. 2 represents a side elevation thereof;

Figs. 2a and 2b represent, respectively, Va broken side elevation, partially in section, and an elevation of the open end of an ice cream container;

Fig. 3 representsra vertical longitudinal section taken in the plane indicated by the line III-III, Fig. 1;

Fig. 4 represents a righthand end elevation' 5 represents a vertical transverse section taken in the plane indicated by the line V-V, Fig.V 1;

Figs. 6 and 7 represent, respectively, side and end elevations of one of a series of long cutting blades Vhereinafter more fully described; Y n p Figs. 8 and 9 represent, respectively, side and end elevations of one of a series of short cutting blades; p

Figs. 10 and 11 p represent, respectively, side and bottom plan views of said longand short blades assembled;

. Fig. 12 represents a perspective` of a block of cream ,after being cut into individual portionsby means of my invention,

Figs-13 'and 14 represent, respectively, an end View and a section in the Vplane indicated by the line XIV-XIV, Fig. 13, of a hood vutilized to prevent the cream from being displaced when certain separators serving to segregate the different colored creams are being withdrawn from the container into which the creams have been poured;

Figs. 15 and 16y represent, respectively, .side and plan views of the separators before mentioned.

Referring to the annexed drawings, a base for my improved machine is indicated by the ordinal 1, upon which at one end in two brackets 2 and 3 is journaled a shaft 4 carrying at one end a gear 5 and at the other end four, pulleys 6, 7 8 and 9, of which pulleys 6 and 7 are power. pulleys, direct and reverse, respectively, land 8 and 9 are idlers. Power is furnished from the pulley 12 and belts 10 and 11 connectsaid power pulley 12 with the sets of pulleys'6-8 and 7 9, respectively. l

Opposite motions for the pulleys 6 and 7 are producedby meansrof crossing the belt- 10. The gear 5 meshes with a gear 13 which is, in reality, a nut, being provided with an internal thread adapted to coperate with a worm 2G.v ,This worm is mounted in two bearings 18 and 19,.of which the bearing 18 is amovable one, being mounted upon two rods 16 and 17 which are supported in brackets 14 and 15. The screw 2O is formed with an outer hub portion 21 carrying a head 22 servingas a push plate for forcing a block of ice cream out of a container, as hereinafter fully described. It is evident that the actuation of the belt 10'iri the directionindicated by the arrow in Fig. 2 will result in the outward movement of the screw 2O through the bearing 19, the bea-ring 18 sliding with the inner end of the screw upon theiods 16 and 17. Two belt Shifters 23 and 25, respectively, are secured to the movable bearing 18 the same being provided with lingers 24 and 26, respectively, which, at or about `the end of the outward movement of the screw '20 contact with the beltslO and 11 respectively to shift the 'same onto the idler 8 and the active reverse pulley 7, respectively, resulting in the return movement of thev screw. At or about the end of this return movement ythe belt 11 is shiftedfrom the active reverse pulley 7 to the idler 9 by means of a finger 27, plainly shown in Fig. 2. so that both belt-s 10 and11 then are running upon idler pulleys.

The forward movement of the bearing kao Vupon portion having a connecting rod34 secured p at its inner end to a movable frame 35 from which depend four pillars 36. To the bottom of these pillars 36 is secured a casting 37 adapted to support the cutting kblades which will now be described. vReof twov series of blades and, in the form of Vdevice herein described, and shown in the accompanying drawings, each series of blades consists of nine blades. One Vof these series are long blades and the other series comparatively short blades. The short blades 38 are provided with slits 38 of a width substantially equal to the thickness of the blades and the long blades 39 are provided with slits 39 of substantially the same thickness. The blades 38 and 39 are ofV substantially the same depth and are assembled by means of mounting the short cross blades 38 upon the longlongitudinal blades 39, the tongues of the short blades 38 between the respective .contiguous slits 38.

being-disposed between the respective contiguous long blades 39, as plainly shown in Figs. 10 and 11. It is evident that the i proper actuation of an assembly of blades detail.

just described would result, during one cutting laction, in the slicing of a block of cream, of the character shown in Fig. 12, into sixty-four portions, as plainly shown in saidgfigure. Such an actuation of the assembled blades will now be described in As hereinbefore mentioned,. the blades are supported uponthe movable casting 37. 1n detail,this support consists in hooking the respective projecting shoulders 382 and 39.2, formed upon the bottom end .portions Vofthe blades 38 and 39,.under the casting 37 and then securing the assembled blades to said casting by means of two endpins 40 passed through the long blades 39 and secured at their two ends in the casting 37, as plainly shown in Fig. 5. Secured to the Vshaft 33 exteriorly of the gear 31, is a ratchet Y 58 adapted to coperate withV a pawl 59 secured to the gear 31. It is evident that the actuation of the gear 30 in the direction indicated by the arrow in Fig. 2, due to the `forward movement of the rack 29, will result in the actuation of the gear 31 in the in Figs. 2, 3 and 5.

figure, and that the pawl 59 will play idly over the ratchet 58 and there is no rotation of the shaft 33. `The actuation of the gear 31 in the opposite direction, due to the retraction of the rack 29, will result in the action of the pawl 59, and the consequent rotation of the shaft 33. This will result in the movement of the casting 37 downwardly and upwardly and the cuttingv action of the blades 38 and 39.

Before the above-described cutting action has taken place, and during theforward movementY of the screw 2O andrack 29, the large block of cream has been deposited upon a board 47 supported upon the platform 45 and upon which board the cream is later cut by the action'hereinbefore described.` This cream has been forced out ,of a can .50 by means of the -head`22 during the forward movement ofthe screw 20. The cream has been contained in a boxV 50 which has been placed upon supporting brackets 51 mounted movement of the ratchet 58, due to the upon the main base 1. The forward moveing lblades 38 and 39, I provide strippers49,

plainly shown in Figs. 3 and 5, dependently `supported from av platform 44, whichV is. mounted upon a shoulder 48 of a frame'42,

which in turn iss'upported by hangers 41 forming at their upper portions bearings Vfor the crankshaft 33. Theplatform 44 is spaced from the frame 42 by four transverse stiingers 43, plainly shown in Figs. 2 and 3.

The whole stationary frame supporting the strippers 49 and forming bearings for the crank shaft 43 is supported uponthe pillars 32 by means ofthe screwv 61, plainly shown,k

The block of cream illustratedin Fig. 12 is formed as follows: The box k5() is stood upon one end, formed by sheet metal plates A53 and 53, secured together by means of a screw 55and separated by a leather gasket ,54, by Vmeans of which any wear mayV be taken Vup and' leakage prevented, and the placed over the open end-of the lbozrV 50, this A Y, hood having a shoulderportion57 disposed over the contiguouslateral portion ofthe .y

box and alsotwo slits-'57,2 through which by a suitable instrument, such as a hook, the separators 56 may be withdrawn from the box 50.
